Ion selective electrodes and microelectrodes are commercially available for more than 20 common anions and cations and have found applications in many branches of science. The potential of an ion-selective electrode allows the direct measurement of ion concentrations, providing a rapid and convenient means of quantitative estimations of numerous important cations and anions in free unassociated form.
This paper reports our preliminary findings on the potential applications of the silver ion-selective rnicroelectrode to the forensic analysis of adulterated jewellery.
Criminal investigations may require the identity (qualitative) and the quality (quantitative) aspects of metal or jewellery to be established. This arises in such cases as robberies where items have been seized and the court wishes to identify the origin of the metal or piece of jewellery, or in cases of fraud where items were purported to be of a certain identity or quality.
